PvZ is actually REALLY good for what it is, a slimmed-down casual tower defense game. It has that addictive quality that a lot of these have, and I had way more fun with it than I should have(Steam says I put 32 hours in before I finally stopped).

For the love of god, do NOT buy this. I tried it, and it is a terrible, terrible game. Even at this price, stay away.

Oh, and there's also DLC for... Serious Sam HD: The Second Encounter? The hell? Anyway, as a result, the Serious Sam Complete Pack, which has EVERY SINGLE SERIOUS SAM GAME AVAILABLE ON STEAM, is 75% off at £16.25 / $21.75, which is an excellent price for all the stuff you get.(For the record, that's both the original and HD versions of The First & Second Encounters, this DLC, Serious Sam II, Serious Sam 3: BFE, Double D and The Random Encounter).
